Comment 1 for bug 1790534

Hmm, FWIW that is a debug build. But I just tested the same board on linux with master and I see the following assert thing on the console. I don't know why I don't see the usual wx assert dialog.

kicad: /home/wee/woo/kicad-src/include/geometry/polygon_triangulation.h:389: void PolygonTriangulation::earcutList(PolygonTriangulation::Vertex*, int): Assertion `aPoint->prev == aPoint->next' failed.

It looks like it shows some of the 3D viewer window frame, except for the canvas area which shows the window below. The status line in the bottom of the window shows "Build Tech Layers".
